Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Press the firm tofu for at least 15 minutes using a tofu press or heavy skillet to remove excess moisture, then cut into 1-inch uniform cubes.
Place the broccoli florets and sliced red bell pepper on the baking sheet, drizzle with olive oil, and season with sea salt and black pepper.
Roast the vegetables in the oven for 15 to 20 minutes until they are tender and show slight charred edges.
While the vegetables roast, place the tofu cubes in a bowl and toss thoroughly with nutritional yeast and garlic powder until evenly coated.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Add the coated tofu to the skillet and sear for 3 to 4 minutes per side until each edge is golden brown and crispy.
Lower the heat and stir in the shelled edamame and tamari, tossing for 2 minutes until the tofu is glazed and the edamame is heated through.
Remove the roasted vegetables from the oven and combine them with the tofu mixture before serving warm.
